- food ingested from oral cavity to the esophagus
- air traveling from the oral cavity to the esophagus
esophagus
extending from the pharynx to the stomach
- uses peristalsis
- connects to stomach through the lower esophageal sphincter (LES)
Deglutition
food moves into the esophagus
- bolus –> closed larynx and trachea through movement of epiglottis –> esophagus –> epiglottis opens again
pharyng/o

bigger curve on bottom of stomach
lesser curvature
smaller curve on top of stomach
antrum
after the body

ring of muscle that controls the chyme from entering the small intestine
rugae
folds in the mucous membrane lining in the stomach
gastr/o
stomach
pylor/o

duodenum, jejunum, Ileum
duodenum
receives mixture of biles and lined with villi, major site of digestion
villi
